WlRE-STRETCHER.

Specification of Letters Patent.

Patented Dec. 1 1, 1906.

Application filed December 4.,1905. Serial No. 290,246.

To all whom, it may concern:

Be it known that I, WALTER P. CnIsHoLM, a citizen of the United States,residing at Sherman, in the county of Greyson, State of Texas, haveinvented certain new and useful Improvements in Wire-Stretchers and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention has relation to stretching wire for any purposeas, forinstance, to get it in the best condition for fastening it to posts orpoles in building fences or for splicing it or for any other reason.

It is the object of the invention to provide a wire-stretcher which willbe at once convenient and ready for use in all respects for which it isintended and be simple and strong, making it durable and handy.

The invention consists of parts and a combination of parts which whenassociated and combined, as hereinafter set forth, and pointed out withparticularity in the subjoined claims will constitute a new and improvedcontrivance for the purposes specified.

Reference is to be had to the annexed drawings, and to the letters ofreference marked on the same, forming a part of this specification.

In the drawings, Figure l is a plan view of the complete machine. Fig. 2is a side elevation. Fig. 3 is a separate view of the wireholding deviceand its jaws. Fig. 4 is a vertical longitudinal section on line 4 4 ofFig. 1. Fig. 5 is a section on line 5 5 of Fig. 1.

The same letters of reference show the same parts or features, as thecase may be, wherever they occur.

In the drawings, a designates the main frame of the machine, which ismade of suitable material and strength, as well as shape. On oppositesides of the contracted portion b of the rear end of the frame on oneside is a staple or eyed bolt 0, to which one end of the chain (1 to bepassed about a post a or similar means is fastened, the said chain beingfor the purpose of adjustment to a hook f at the other side. Suitablemeans, as a pivot-bolt g, is provided between the sides of the frame,

on which the rear end of the pawl it may be pivoted. .Pawl h is arrangedat its free end to engage the teeth of ratchet-wheel "L, forwardlyrotated by a crank j, secured to the drum-like shaft is, upon which therope I is wound, the pawl preventing any slipping or backward movementof said ratchet-wheel, as readily understood. A disk m may be arrangedon the shaft is to assist in guiding the rope as it is wound to place.

0 is a tri-iron, being a piece with three arms having holes or otherfastening means formed therein. To the end of the rearwardly extendingarm p the forward end of the rope may be tied, and to the forward endsof the side arms one of the ends of the links 9 r may be secured, theother ends of said links (1 1' being connected to the lever arms 8 t ofthe wire-holder u, the jaws o of which are represented in Fig. 3. Thewire passes between the jaws v and may be temporarily connected to therear end of the rope by any suitable means.

In operation all of the functions of the parts are clear to thoseskilled in the art by an inspection of the drawings. The chain (Z willbe passed about a post or pole or other suitable means and fastened, andthe crank may be put on the squared end of the shaft is, or it may bescrewed thereon or fastened in any desirable way, and one end of therope I may be fastened to the shaft 76 in any suitable way, while theother end may be attached to the rearwardly-extending arm 2) of thetri-iron 0. All of the other parts being arranged as stated, byoperating the crank and winding up. the rope eventually a pull with anydegree of tension may be made on the wire, as will be understood.Splicing may be effected by simply passing the proj ecting end of thepiece to be spliced through the jaws of a separate wire-holder and usinganother set on the wire-holder, as explained.

What is claimed is A wire-stretching device comprising a frame includingmeans for its attachment to a post a shaft journaled in said frame; adrum mounted on said shaft; a rope attached at one end to said drum; atri-iron secured to the opposite end of said rope; links secured to theforward arms of said tri-iron; a wireholding member secured at its rearend to the opposite end of each link, said wire-holding verse movementof said shaft and consequent members being pivoted togetherintermeloosening of said jaws from the wire. 1o diate their ends andprovided at their for- In testimony whereof I affix my signature wardends with jaws; means for rotating in presence of two witnesses.
